What should Authenticate Fetch from a User?
I joined a group that has been using Django and I was just curious for some performance aspects of user fetching for Authentication. The User objects have some foreignkeys/manytomany fields attached to them. I learned about the prefetch_related / select_related. So if I want to get everything of a user instance, that would result to about 10 queries. So my question is about API / REST Design. Should my auth only do 1 Query ( select User) or should it fetch alle the stuff that could be useful for other endpoints? Each endpoint uses the CustomAuthentication, so the queries would be executed for each API call. Is ist better to let people take care of a second well designed query at the endpoint, or should I provide them with alle variables on each endpoint autmatically ? Thanks in advance. This question is performance related. I tracked the requests with SILK and was not happy about the performance for retrieving Users -
How to return a list of objects using a Django REST API post request?
I am new to using REST API's and am trying to create an API where I can make a POST request containing keywords, which should then return a list of articles related to that keyword. The reason I can't use a GET request is because I am not GETting anything from a database, I am creating the list of articles based on the keyword from the POST request. Views.py: def article_get(request): if request.method == 'POST': serializer = serializers.ArticleListSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) classes.py: class Article: title = "" url = "" def __init__(self, url, title): self.title = title self.url = url class ArticleList: keywords = "" articles = [] def __init__(self, keywords, articles): self.keywords = keywords self.articles = articles self.articles.append(serializedArticle) The self.articles.append(serializedArticle) line appends a serialized article to the articles list, which I hoped would simply add an article in JSON format to the articlelist, but instead it produces the following error: Object of type ArticleSerializer is not JSON serializable serializers.py: class ArticleSerializer(serializers.Serializer): title = serializers.CharField(max_length=300) url = serializers.CharField(max_length=300) def create(self, validated_data): return classes.Article(**validated_data) class ArticleListSerializer(serializers.Serializer): articles = serializers.ListField() keywords = serializers.CharField(max_length=100) def create(self, validated_data): return classes.ArticleList(**validated_data) As I mentioned, I am FAR from being … -

django rest framework serializer, create an object for some model field

While testing a Django form, I'm getting the following error: `Select a valid choice. That choice is not one of the available choices.`
Context I have a Django form to create events (which is working well in the UI) and now I am creating the unit test. My event model has two foreign key fields: category and location, pointing to the models Category and Venue respectively. The Category and Venue models have a property public_id to prevent exposing the real ID in the select form. The Issue When I try to test the form, I can't figure out how to make it pass.

Django merging or joining more then 30 models with same fields into one?
so i need to build rest api with django rest framework and the problem that i have is that I've got more then 30 models from already existing postgresql db with command inspect db. All these tables have exactly the same fields. They are collecting data in different countries so I can't change anything regarding db but i need to build api. Also there is more then 1 000 000 instances in all tables and the data is updating almost every day. Is there a way that i can join these tables into one. What would be the best way to serialize this and send it with view? Any idea is welcome. Thanks -

Django: Pass a variable back into views
I'm writing a sudoku webpage with Django and JS so I'm passing my unsolved sudoku list into the page via the context dictionary. In the page, I have 2 buttons in a simple HTML form. If 'NEW' is selected, it refreshes the page with a new sudoku. If 'SOLVE' is selected, I want it to send the current sudoku list back into views to go through the solver function and then sent back into the template. I currently have everything working except I have no idea how to send the unsolved sudoku list back into views. I've seen a lot of responses to questions like this saying to use request.POST.get() but how would I get the list into the queryDict? Also, I can't seem to find any posts on this topic within the last decade or so. Correct me if I'm wrong, but I think Python and Django may have changed slightly in the last 10 - 15 years. -

Django Test Error: "1824, Failed to open the referenced table"
This is the flow of how my database is created: I already have a legacy MySql database with some tables. I create the django project and connect it to the legacy database. I run migrate, in order to create the django tables for sessions and authentication on the legacy DB. Then, directly from the DB I create the GeSession Table and the reference to the DjangoSession Table. Then I import all the tables models using "inspectdb" command. To be able to test, inside models.py, I set managed = True to every table except for the django ones. Then I run makeMigrations and migrate --fake-initial. If I try to use the django ORM to make queries it works without any problem, but during testing it keeps failing the test database creation giving me this error: MySQLdb.OperationalError: (1824, "Failed to open the referenced table 'django_session'") and then right after: django.db.utils.OperationalError: (1824, "Failed to open the referenced table 'django_session'") Everytime I tweak something on the models.py file I delete the first migration file, I run makemigrations and then run: migrate --fake-initial.

Swagger is using schema host instead of current server
I am working with swagger , Django. I have used drf-spectural library. I have created one schema.yaml using openApi docs. And i have one docs/api/ API Url for swagger documentation . When i am executing API from documentation it is taking Host url of static file instead of my current server. for example :- my schema file is place of s3 bucket, The Url is https://bucket.awss-s3.com/folder/schema.yaml and my server url is https://sub-domain.example.com/docs/api/ and my example api url is https://sub-domain.example.com/api/get-product/ but when executing from swagger it is taking https://bucket.awss-s3.com/api/get-product/ So my swagger config are SPECTACULAR_SETTINGS = { "SWAGGER_UI_SETTINGS": { "url": "/static/schema.yaml" } }
